Nov 30, 2018 at 2:55 | comment | added | Damien | Actually it is not that correct. It is a general assumption that linear regulator gives a smooth output. But in fact, it might be worse than a well done buck with filtering. The linear regulator are not good at ripple rejection, if you have an input with ripple, the output will also have significant ripple. Also linear regulator do oscillate on their own and varies depending on the current and capacitive load (capacitive load which varies over temperature if you use ceramic caps, thus you have a temperature dependent ripple). | |

Added commentary on option 3.
